FIG. 6. 8

INVENTOR HERMAN KOE HL www ATTORNEY Y2,996,211 'COMBINATION PUNCHING AND EYELETING DEVICE Herman Koehl, N. Main St., Danielson, Conn. 'Filed Jan. 2, 1959, Ser. No. '784,761 4 Claims. (Cl. 218-125) The present invention relates to a combination punching and eyeleting device in general and to such a device which is operated by means of la hammer or the like.

Combination punching and eyeleting machines are known which comprise a plurality of parts, including pliers or oppositely disposed jaws forming, respectively, the anvil and hammer jaws of the eyelet setting mech-anism. Yet, the recognition that the average home-maker desires the making of dresses, belts, bags, curtains, and the like at home, brought to the market the sale of eyelets, in the same manner as buttons, buckles, or the like are distributed on the open market. This possibility necessitates in turn some tools which lend themselves easily to operation by the homemaker. The tool-s, as pliers or other eyeleting machines are, however, either expensive and thus prohibitive for home use or not practical and complicated in their operation, particularly since their use requires experience and familiarity of operation of such tools, which is mostly lacking with the average homemaker.

It is, therefore, one object of the ,present invention to provide a combination punching and eyeleting device, which removes all the mentioned drawbacks of the known tools or machines and which may be handled by the average homemaker with greatest ease, without the slightest diiiiculty and without any experience.

It is another object of the present invention to provide a combination punching and eyeleting device, which lends itself to such economical manufacture that it can be added free of charge to a sale of a cardboard having a plurality of eyelets mounted thereon.

Itis still another object of the present invention to provide a combination punching and eyeleting device which comprises a hat metal strip one end of which is formed integrally as a punching device and the other end of which is formed integrally as an eyeleting device.

With these and other objects in View which will become apparent in the following detailed description, the present invention will be clearly understood in connection with the accompanying drawing, in which:

FIGURE l is a top plan View of the punching and eyeleting device deisgned in accordance with the present invention;

FIG. 2 is a section along the lines 2-2 of FIG. l;

FIG. 3 is a section of the device at a stage after punching a hole through the material;

FIG. 4 is a cross-section lthrough the punched material with inserted open eyelet;

FIG. 5 is a section of the device with the material at a stage immediately after clenching the open end of the eyelet inserted in the punched hole; and

F-IG. 6 is a section through the material with inserted eyelet having it open end rolled over.

Referring now to the drawing, and in particular to FIGS. 1 and 2, the punching and eyeleting device comprises a flat, short metal strip 1 which is formed integrally adjacent one end into a tube 3 defining 'a cylindrical opening 2, the top end of the opening 2 being flush with the top face of the metal strip 1, while the `bottom end of the opening 2 is spaced apart from the bottom face of the metal strip 1 and the outer face of the :tube 3 is tapered downwardly to form a sharp circular cutting edge 4 at said bottom end of the opening 2, to operate as a punching device.

'United States Patent 2,996,211 Patented Aug. 15,"1961 Ice,

The metal strip 1 is formed integrally adjacent its other end into an `eyeleting device which has a central stud `5, projecting beyond the top surface of the metal strip 1, and an annular groove 6 kdisposed below the top face of the metal strip l1 and extending with its bottom face below the bottom face of the metal I'strip 1, said annular groove surrounding the central stud "5.

A measuring scale 7 is provided on the top face of the metal strip 1, in order to permit punches at equal distances and, preferably, along a center line of the material to be punched, as -a belt.

The operation of punching and eyeleting of the combination punching and eyeleting -device is performed in the following manner:

Referring now to FIG. 3, the punching of a belt 8 having a layer of material 9 on its top face is disclosed by applying the device designed in accordance with the present invention.

The belt tlV with its layer of material 9 is placed on a Abase 10 `and by gripping the end of the metal strip 1 which forms the eyeleting Idevice and applying the end of the metal ystrip which forms the punching device to the top Vface of the layer 9 in such a manner that the sharp cutting `11 of the belt with its layer `of material is punched out, which circular portion 11 is received in the cylindrical opening 2 ofthe punching device. The height of the tube 3 is, preferably, chosen equal with the thickness of the material to be punched, namely the combined thickness of the belt 8 and the layer of material 9. In this manner it is avoided that the base 10 is Kappreciably damaged, since the tube 3 cannot penetrate for a length greater than the heighth of the tube 3 (FIG. 2). This is of some importance, since a magazine book or the like will usually be available, -to be used as the base 10 by the homemaker.

Upon finishing the punching operation, the device is removed from the punched material and 4an eyelet 12 is inserted into the punched hole with the post 13 of the eyelet 12 directed upwardly, as shown in FIG. 4 of the drawing, in such a manner that the punched material is preferably reversed, so that the layer of material 9 is now on the bottom and the belt material 8 is on top, whereby the lower rolled-over end of the eyelet 12 engages the layer of material 8 and the post 13 of the eyelet 12 projects beyond the top face of the belt 8.

Now the device is put into operation again, first by reversing the same so that the previous upper face thereof assumes now a position to constitute its lower face and using the end forming the punching device as a handle to grip the device with one hand. The now downwardly projecting central stud 5 enters the upper end of the hol-low post 13 of the eyelet 12, and by a blow of a hammer (not shown) or a similar tool upon the top of the eyeleting device, the annular groove 6 of the latter acts to turn over or to roll over the upper end of the hollow post 13 of the eyelet 12, so that the upper edge of the hollow post 13 of the eyelet 12 is clamped upon the material into which the eyelet 12 has been inserted, to assume the position indicated in FIG. 5 of the drawing. It is to be understood that the eyeleting device must be cornplementary to the eyelet, as far as the size is concerned, since for proper operation it is required that Ithe outer diameter of the central stud 5 must correspond with the inner diameter of the hollow post 13 of the eyelet 12 and thus may center the eyeleting device and to provide a guide during the roll-over step of the upper end of the hollow post of the eyelet. The predetermined height of the central stud 5 limits also the extent to which said hollow post of the eyelet is rolled over.

strips.

While particular means are required in known combination punching and eyeleting machines to render inoperative the punching lapparatus of the machine during the eyeleting process, in the present device the tube 3 does not interfere with the eyeleting step, since it is at the remote end of the metal strip 1 and merely renders rigidity to the metal strip 1 while forming part of the handle during the eyeleting step.

Though it is preferred to form both devices, namely the punching device and the eyeleting device by integral forming on a single ilat metal strip, it is also possible to provide each of said devices on separate at metal strips by forming the respective devices integrally from said metal The shape or configuration of the punching device and that of the eyeleting device is subject to change in accordance with any particular requirements.

While I have disclosed one embodiment of the present invention, it is to be understood that this embodiment is `given by example only and not in a limiting sense, the scope of the present invention being determined by the 'objects and the claims.

I claim:
